Abstract The self-made analysis system of three-dimensional(3D) visualization，named SlopeMoni3D and developed for safety monitoring of rock slope engineering，is used to establish safety monitoring distributed analysis platform for the left bank high slope of Jinping I hydropower station；then the virtual reality visual analysis of the safety monitoring system and occurrence of slope geological conditions is realized. The development tendency of superficial，deep deformation and the spatial distribution of anchoring force of cable dynamometers at the same period in the excavation area of the left bank slope，which is obtained by safety monitoring，are comprehensively analyzed in the form of three-dimensional nephogram visualization. The analysis and evaluation of overall slope stability and deformation tendency are completed. The analysis results indicate that：(1) Using virtual reality visualization technology to resolve regional engineering geological conditions of complicated rock slope，we can directly express the relationship between monitoring points arrangement of each monitoring project and its geological structures and easily realize the comprehensive analysis based on monitoring results，geological conditions and construction information. (2) By virtue of the functions of monitoring data management and 3D nephogram rendering based on monitoring data fields，which are provided by SlopeMoni3D，we can directly compare the 3D nephogram distribution of obtained monitoring physical quantities of different monitoring projects at the same monitoring period；and it is convenient for analyzing the regional deformation tendency and overall stability status from various aspects of geology and construction.
